I bought one of those double sided tape applicators and used them to line 100 clips in various colors to use on my big bows. Today as I was setting out some new bows to sell, I noticed one of the clips had the ribbon separating from it. So I examined it further and sure enough, that tape wasn't holding.
I had to pull out my glue gun and go over all of them again! Just imagine a customer putting one in their child's hair after a couple of wears and having the ribbon let go of the clip because the double sided tape isn't strong enough.
That stuff holds for a while but it's bad when it starts falling apart after the bow has been purchased. Junk. Never again. I'm sticking with my glue gun.
